The game is pretty much exactly what you would expect it to be, which is Picross with Twilight Princess references. Along with Twilight Princess themed puzzles, the game also includes sound effects and music, including the iconic "da da da!" victory jingle (in this case, played whenever you complete a puzzle). You're given plenty of time to complete the puzzles (there's a 60-minute time limit), and various hint options, such as options for the game to tell you when you've made a mistake at the expense of a time penalty. There's also a nice feature where the game will show you in blue which columns/rows you can currently fill in. You can choose between touchscreen controls or buttons, and if you use touchscreen controls you can also use the control stick or D-pad to toggle between filling in squares or marking them with an X. One surprise was that the game includes "Mega Picross" puzzles, which have a variation of the regular Picross rules and offer a nice change of pace (apparently these are also included in Pokémon Picross, although I guess I got bored of that game before I got far enough along to encounter them).

This was a fun game and the Twilight Princess elements gave me a nice feeling of nostalgia. Nothing earth-shattering, but a good game to unwind with.
